too-large notches in boxplot (PR #7690)
PR #7690 points out that if the confidence intervals (+/-1.58
IQR/sqrt(n)) in a boxplot with notch=TRUE are larger than the
hinges -- which is most likely to happen for small n and asymmetric
distributions -- the resulting plot is ugly, e.g.:
set.seed(1001)
npts <- 5
X <- rnorm(2*npts,rep(3:4,each=npts),sd=1)
f <- factor(rep(1:2,each=npts))
boxplot(X~f)
boxplot(X~f,notch=TRUE)

Strange horns on notched box plots
Hi I'm getting a weird result when I try to switch from a normal box
plot to a notched one. The ends of the box fold down toward the
median giving a horned appearance. Is just the sample itself? It is
small, but the un-notched plot looks okay. Anyway to fix this?
e7=as.vector(c(234,37,98,116,47))
boxplot(e7, plot=TRUE, notch=TRUE)
Thanks very much.

boxplot, notches, etc.
Sorry to repost this, but it looks like it's getting
buried in r-help (originally posted October 5: my experience
says that if it hasn't been answered by then it won't be).
I wouldn't bother, but I'm worried that r-devel might be
better, *and* a previous e-mail of mine on the subject in
January also seemed to get buried.

boxplot notches
Dear list members,
Can anyone tell me how the notches in boxplot(Y~X,notch=T) are
calculated? What do these notches represent exactly? I?d suppose they
are Conficence Intervals for the median, but I?ve also been told they
might show Least Significant Difference (LSD) equivalents.
I would very much appreciate any help from you.
Best regards
Chris.

Plotting Notched Box Plots Log Scale - Losing bottom portion of box plot
Hello,
I'm using the code below to generate some notched box plots. The issue is
whenever I use log scale, the sides of the bottom part of the box plots
don't plot. I've tried it in RStudio Ver 1.1.419 and R version 3.4.3 and I
get the same result.
The code and link to my data is below.
Thank you for your time

unexpected behavior of boxplot(x, notch=TRUE, log="y")
A function I've been using for a while returned a surprising [to me,
given the data] error recently:
Error in plot.window(xlim, ylim, log, asp, ...) :
Logarithmic axis must have positive limits
After some digging I realized what was going on:

How to produce notches in bwplot?
Dear r-helpers,
tst <- data.frame(as.numeric(x <- 1:20), f <- rep(c('hi','lo'), times

with(tst, bwplot(f ~ x, panel = function(x, y){panel.bwplot(x, y, pch

I can't figure out from the documentation how to tell stats that I
would like to see notches or (even bands).

Notch Filter in AEC
Hi,
The notch filter in AEC is only used to remove DC signal, and the time of convergence is not important, right?
If so, I think preset value of notch_radius is too small, and it causes noticeable distortion(freq < 200hz cut).
There is a picture in attachment to show signals under different radius in time-domain.
By setting notch_radius to 0.999 for all sampling rates, I found better

ggplot2 box plot notches
Dear List,
I just googled to find out if notched box plots are possible with
ggplot2, but couldn't find a answer to it.
boxplot() has the option: notch = TRUE, e.g.: boxplot(mpg$hwy, notch=TRUE)
My example code (taken from the net) is:
require(ggplot2)
qplot(class, hwy, fill=factor(year), data=mpg, geom="boxplot",

Error message when using error.bars(x,add=TRUE)
Hey hey,
I`m analyzing a data set containing the element contentrations of various
samples...
I wanted to construct notched boxplots and got quite ugly results for some
of the boxplots. The notches are often larger then the hinges which resulted
in weird looking edges (even though I`m using a log-boxplot). To avoid this
problem I thought about using "normal" log-boxplots and adding some kind of
parantheses for...

Adding Mean to Notched Box Plots
Hello everyone,
I'm new to R and made my 1st notched box plots this weekend. I've read some
of the other post regarding adding means to box plots but I'm still having
problems.
I've looked at some of the other discussions and R News Volume 3/2, October
2003 which had info also but all these seem to address "groups" of data....

Choice of notch size in R
Is there a way to modify the choice of notch size [1] in R's boxplot
routine from outlining a 5% significance region, to say 1% or lower?
Thanks,

date library and notched boxplots
I'm having problems using the date library with notched boxplots. I have separate month, day, and year columns and would like to plot the columns as a date against other variables. I have used the mdy.date(month,day,year) command before with plot(), but it doesn't seem to work with boxplot(). Instead of the dates along the x-axis, I get a list of...

Notch Filter in AEC
Hi Jean-Marc,
You make that sound like its just a matter of meeting some arbitrary
spec. Let's be more specific.....
If you use narrow band voice down to deep bass frequencies:
- 16 bit linear audio sounds good
- alaw or ulaw sounds muddy
- low bit rate codecs, like speex or G.729, sound awful.
I assume QinBin only listened to some uncompressed audio in his evaluation.

But in fact, it really affects the voice quality. One of my tester says, "Is your mouth far way from the mic?"
Could you explain why we should cut 200hz below?

Notch Filter in AEC
The notch filter is specifically designed to cut below 200 Hz when
working in narrowband. In wideband, the cutoff is more around 50 Hz. The
reason is that in narrowband operation (irrespective of the codec),
you're not really supposed to have anything below ~200 Hz, but a lot of
people forget that.
